Yuasa HGV batteries at Truckstop Group
Yuasa is one of the most widely used battery brands in the commercial vehicle sector. Their heavy-duty range is designed for the high cyclic demands of modern HGVs, where stop-start systems, cab electronics, and ancillary equipment place significant load on the battery system during rest periods. Yuasa commercial batteries are built to handle this without the accelerated capacity loss that affects standard automotive batteries under the same conditions.
HGV batteries are rated in Cold Cranking Amps (CCA) and Ampere Hours (Ah). The CCA determines starting performance in cold conditions: most modern turbocharged diesel HGVs require batteries with a CCA rating of 900 to 1400A per battery depending on engine displacement. The Ah rating determines how long the battery can sustain ancillary loads during cab rest time, which is particularly relevant on vehicles with cab refrigeration, inverters, or multiple charging points.
Most trucks run two or three 12V batteries wired in parallel to achieve the required CCA and capacity. When replacing batteries, replace all batteries in the bank at the same time: mixing an old battery with a new one causes the new battery to carry a disproportionate share of the load and shortens its life.

Frequently Asked Questions
What Yuasa batteries does Truckstop Group stock for HGVs?
We stock Yuasa heavy-duty commercial batteries in the most common HGV sizes and CCA ratings. The range covers standard flooded lead-acid batteries and maintenance-free AGM variants for trucks with higher ancillary loads. Call us with your vehicle make, model, and engine specification and we'll confirm the correct Yuasa battery.
How do I know if my HGV battery needs replacing?
The main signs are slow cranking on start-up, particularly in cold weather, battery warning lights on the dashboard, and the vehicle failing to start after a rest period. A battery test using a conductance tester will give you the battery's state of health as a percentage. Most workshops consider a battery below 60% state of health as due for replacement.
Should I replace all the batteries on my HGV at the same time?
Yes, if you're replacing one battery in a parallel bank, replace all batteries at the same time. Mixing a new battery with worn ones causes the new battery to take a disproportionate charge and discharge burden, which shortens its life significantly and costs more in the long run than replacing the full set.
What is the difference between a standard and AGM HGV battery?
Standard flooded lead-acid batteries are the most common type and suit most HGV applications. AGM (Absorbent Glass Mat) batteries are sealed, spill-proof, and better suited to vehicles with high ancillary loads, stop-start systems, or where the battery is mounted in a non-upright position. AGM batteries tolerate deeper discharge cycles better than standard batteries and recover more reliably from partial discharge.
